CPT code 72128: Spine CT, thoracic, no contrast2026 Medicare rate & RVUs

Medicare pays $130.26 for 72128 nationally in the office. Local office rates run $115.71–$174.85.

Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 72128 covers

This study uses computed tomography to create cross-sectional images of the thoracic spine without contrast material. It is commonly performed in a hospital or imaging center when clinicians need detailed bony evaluation, such as after trauma with suspected vertebral fracture or when radiographs do not adequately show a thoracic spinal abnormality. A radiologist interprets the images; the technical service includes the scanner, acquisition, and supporting staff.

Report this code for a thoracic spine CT performed without contrast, not for a cervical or lumbar study or a scan that includes contrast. The imaging report and order should support the body region and contrast protocol. A claim without a component modifier represents the global service; modifier 26 identifies the interpretation, and modifier TC identifies the technical service. When multiple diagnostic imaging procedures are reported, CMS applies the multiple-procedure reduction to both the professional and technical components.
